During a comprehensive process review of the Daphne Utilities wastewater treatment facility in 2009, chokepoints were discovered in the headworks equipment at the “front door” of the plant and in the effluent outfall line at the “back door”. These conditions prevented the plant from reaching its full permitted capacity of 4.17 MGD. Peak flows exceeded hydraulic capacities for both the outfall line and the headworks, while the headworks also faced high influent concentrations of BOD and TSS that exceeded design. Upgrade projects on both systems were successfully executed which not only restored lost capacity but also accommodated a new higher peak flow capacity of 9 MGD. By utilizing new screening technologies, sizeable reductions in influent BOD and TSS levels were also realized creating surplus capacity. This can be utilized in the future to reduce the amount of “new plant” required for construction at a later date.
